Brassicas (Kale, Chou, Rape, Turnips and Swedes), fodderbeet, Italian ryegrass and oats can all produce nitrate toxicity. Of this group, rape is the most notorious - winter rape crops continue to gain popularity in this area for heifer grazing.
Before introducing animals to crop this June, we urge that it be tested first. Nitrate test kits can be purchased from any of our clinics, representing a cheap investment. Alternatively bring in samples to be tested by our staff.
